FIAT 100 engine range 1955 to 2000

The Fiat "100 series" engines have been of 4-stroke engines fueled by petrol with 4 cylinders in line.Built from 1955 to 2000. 

History 

The Fiat "100 series" engine are vertical with the distribution chain camshaft mounted in the crankcase , to rods and rocker arms with head in aluminum alloy to 8 valves , 3-shaft crankshaft, with transverse front or rear longitudinal layout produced by the Italian car manufacturer FIAT at Mirafiori and then in Bielsko-Biała from 1955 to 2000 . It was gradually replaced by the FIRE engine starting in 1985.

The " Fiat 600 ", the first subcompact Italian postwar presented in 1955, was equipped with this new engine with 633 cc designed by men of Dante Giacosa in four months, after the previous design of an engine air-cooled turned out to be too advance for the time.

Born as a rear and longitudinal engine, This was able to evolve for a long forty years of production, becoming an engine for modern cars with front-wheel drive , arranged transversely, with displacement gradually increased up to 1050 cm³ and power that rose from 21 hp originating in the A112 70 Abarth .

The engine was inspired by previous experiences made on the " 1100 " engine and introduced with respect to the "Topolino" unit , the single-piece monoblock base instead of four pieces, the overhead valves instead of the lateral ones and the intake manifold integrated in the head .

The first models were fueled by carburettors , while the injection , only single point type, appeared in 1992 , with the obligation of "catalytic converter " for emissions.

The 767 cm³ version (100D engine) was used on the "600D" and on the Fiat 800 and 770 produced in Argentina , the 847 cm³ inverted rotation on the 850 , 133 and " Panda 34 ", the 903 cm³ on the " 850 Sport ”, on the 850T , 900T / E and in a revised version also on the“ 127 ”,“ A112 ”,“ Panda 45 ”,“ Uno 45 ”,“ Koral ”and“ Cinquecento ”. A 965 cm³ version was used in the 1980s from the "A112" and the first series of the Panda 4x4, while the more powerful 1050 cm³ and 70 HP version will be characteristic of the "A112 Abarth".

A multifunctional engine, produced in Italy, Argentina, Spain, Poland and Yugoslavia, adapted to cars with an " all-back " or " all-out " layout , for commercial vehicles and sports cars. It has passed various anti-pollution regulations, with adaptations to electronic injections and catalysts, and has even had applications for avant-garde "biogas" generators. It has also been used in rallies , in tourism and uphill races, as an approach motorization for generations of pilots, up to the "Panda Monza" formula of the 80s . 

Compared to the "Topolino" engine, it featured overhead valves (already introduced on the 1949 500B), camshaft in the crankcase rather than lateral, forced water circulation by pump instead of convective motion ("radiator") , the intake manifold integrated in the fusion of the head and the ignition with points and distributor instead of a magnet.

The type 100 engine was also used, in the 903 cm³ version of the Fiat 127, as the basis of the cogenerator designed by the Fiat Research Center in 1973 , the TOTEM.
